I’m early (mid) forties, but I grew up on a typical mid 60s Jelson estate on the edge of a village. Much of the original part of the village was heated by solid fuel but being on the edge and mostly upwind meant I never noticed.
My Dad talks about growing up in a city in the late 40s and early 50s where, on occasion, late autumn fog combined with coal smoke and early sunset to make it nearly impossible to walk down the street. Having to feel out for walls, kerbs etc to know where you were. He’s one of the few Boomers I know who has absolutely no hankering for ‘the good old days’ because there was no such thing.
